The 2. question or problem i have is the following. if i am at manufacturer 4 in the manu and i click on a product i see the detail view but the menu left should be the same. means that in the menu the manufacturer needs to be actice and open. i hope you understand what i want.

here is an example:

I am in an detailview of an product but the menu left should be the following

-Drinks-Manufacturers - manfacturer 1 - manfacturer 2 - manfacturer 3 - manfacturer 4 <---- this menu should be open and active during i am in the detailview of the product.- Delivery etc.
